The reaction mixture was poured onto ice and made basic with a 50% sodium hydroxide solution while cooling with the addition of more ice. This mixture was extracted with chloroform, combined extracts dried, filtered, and concentrated in vacuo. The residue was crystallized from toluene, weighed 34.5 g. and melted at 148°-150° C. Ten grams was recrystallized twice from toluene, weighed 7.5 g., and melted at 149°-151° C.
